Nothing built by human hands is perfect, so, sure, the program could be improved! Personally I'd like to see an optimization for Athlon; at the expense of having to load different versions for different processor types, I'd like to see seperate "streamlined" versions of the code

Idea for a screensaver for Prime95, let the user specify a directory of picture files and Prime would pick one to display every few minutes. Decoding a JPG or GIF would suck up some cycles but between picture updates Prime would get them all. Cheers... Russ
